Ambiance: 5. Graze checks all the boxes. Outstanding view of capitol building, a modern feel which the restaurant "owns" by using floor to ceiling glass, relatively small tables, and a very crisp/clean look with everything else. As others mentioned a tad loud but that's to be expected given high ceilings, and actually not all that bad considering this fact.
Cost: 3. Agnostic here, I'm assuming for Madison this place is a bit on the pricey side but well worth it given other categories.
Food Quality: 5. Very unique farm-to-table menu with a wide range of food options for those with unique circumstances (Gluten-free, etc.) and a large step up from what was described as "American" cuisine. All ordered dishes were outstanding and despite being from what I would consider different cuisines: sauteed vegetables, bibimbap, oysters, etc. Looking around I'd also feel very safe ordering anything from seasonal menu.
Service: 5. In typical midwestern fashion, folks were extremely friendly and helpful.
When to return: Visit with foodies. Special occasion/celebration. Posting up at a fancy bar for happy hour. Date night. Restaurant with a view. The list goes on.
